4.Using adhesives:

For the moving cone,make the mixed-up adhesives pour into the aperture of the cone and lining plate directly until to fill up.For fixed cone,make the mixed-up adhesive pour into the aperture of the cone and liner plate,fill up the bottom two layers of lining plate,then install the middle and top four layers of lining plate,make the mixed-up adhesives pour into the aperture of the cone and liner plate after sealing well until to fill up.

5.Curing:

Place it to cure for 12-24 hours at room temperature (20 degree),the temperature has great effects on the curing time,the curing is fast for high temperature, and the curing is slow for low temperature,it can be put into use to cure for 12 hours generally in summer,it can be put into use to cure for 24 hours in winter.When the temperature is too low,you should heat it for curing.It is difficult for the BD65 crusher filled special backing adhesive to cure at the below 5 degree environment temperature,it's difficult for the BD66 crusher filled backing epoxy compound to cure at the below -5 degree environment temperature,if the temperature is lower than the specified requirement during using,all need to heat curing to ensure the performance of the product.

Third: Matters need attention

1 The proportion should be accurate during mixing

2 We should make the mixed-up adhesives pour into the cone within the specified time,the BD65 and BD66 operational time are both 15 mins.

3 We should mix them in the ventilation and without open flame place.

Fourth:The comparison between the organic backing material and the Pb-Zn alloy.

1.There are too many air holes after the traditional Pb-Zn alloy curing,can not effectively play the role of the backing,it can form a complete backing after the organic backing materials curing,it's effective in the broken impact force average distribution.

2.Not only the filling effect of the organic backing materials is remarkable,but also has excellent adhesive property,makes the lining plate and cone be solid combination as a whole,to enhance the overall strength of equipment.
